Achemist notices some silvery liquid on the floor in her lab. she wonders if someone accidentally broke a mercury thermometer, but did not thoroughly clean up the mess. she decides to find out of the silver stuff is really mercury. from her tests with the substance, she finds out that the melting point for the liquid is 275 k. a reference book says that the melting point for mercury is -38.87°c. is this substance mercury? explain your answer and show all relevant calculations.

Wo small variable-thrust jets are actuated to keep the spacecraft angular velocity about the z-axis constant at ? 0 = 1.16 rad/s as the two telescoping booms are extended from r1 = 1.18 m to r2 = 4.69 m at a constant rate over a period of 124 seconds. the small 19-kg experiment modules at the ends of the booms may be treated as particles, and the mass of the rigid booms is negligible. determine the necessary thrust t for each jet as a function of time where t = 0 is the time when the telescoping action is begun. after you have the general expression for t, answer the questions. show work.
